The Colony police are looking for information on who plowed into a triathlete while she was riding her bike Wednesday night.
Debbie McGregor has a fractured vertebrae, deep facial cuts and a concussion, but police say she is lucky to be alive.
"Being in good shape probably helped her condition, kept her from going into shock where other people who are not in shape can definitely suffer more," Lt. Darren Brockway said.
The 42-year-old triathlete and Iron Man finisher was riding up a hill on Windhaven Parkway with the sun in her face when a small white or silver car smashed into her bike from behind at 40 mph. The wreck threw her several yards in the air.
McGregor, who was wearing a vest and helmet, was preparing for the White Rock Marathon and Texas' inaugural Iron Man race.
There is not much left of her bicycle.
"There was debris scattered throughout a broad area," Brockway said. "The front tire had been completely separated from the bike, and the victim was lying in the street unconscious and bleeding."
McGregor's riding coach, Gerald Jackson, said he was a half mile away from McGregor, waiting for her to finish her ride. But he didn't know she was in a crash until someone called his phone.
Jackson said he wants to make sure all his riders stay safe by wearing lights when they ride during the day or night.
Police are looking for a small white or silver car with damage to the hood. Anyone with information should call The Colony Police Department at 972-625-1887.
